i citizen of the United States, residing at Lon- -.don, in the county of Laurel andState of Kentucky, have invented a new 'and useful Improvement in Ice-Cream Freezers, of

which the following is a specification, reference being liadto ing.

My improvement relates particularly to means for placing and retaining the freezer can ofiice cream freeze-rs in the' freezer tub.

The object of the invention is to provide stability for the freezer can and Vprevent floating when the ice surrounding the can within the tub becomes melted, and part-ic ularly when such melting occurs while the can is made lighter by the removal there' from oi a. portion-of the ice cream. n this connection it is to be observed that there 1s decided-tendency towardA such floating, bef cause the liquid between the; tub and ther can is heavy on account of the presence of salt therein, while the oils and fats in the ice cream makethe latter of relatively lower specific gravity. The floating of such' ice cream cans is objectionable for several reasv sons, among which may be mentioned the fact that when the can rises 'inthe liquid,

asmaller portion of the can is exposed to the cold of the brine and ice, and the fact that the ice cream inthe can is then more diiiicult to remove'by means of a spoon or other similar instrument;

In my improved apparatus, the lower por tion o the can is detachably engaged in such manner as to be held'ata `iXed height above the bottom ot the tub and so asto leave the can free'to rotate on an upright axis in the usual manner.

ln the accompanying drawings, Figure 1 is a sectional elevation of a mechanism embodyingl my improvementzFig. 2 is a section on the line, 3--3, of Fig. 1, looking ppward; Fig. 3 is a section on the same line looking downward; Fig. Li is a section 4on the line, 1 -Li, oi. Fig. 1, looking downward.

Referring to said drawings, A, is a por bottom, A andsuitably secured thereto, as

by means of screws, 1, l. Said base converges from the bottom upward and termispeciacation of Letter Patent the accompanying draw.

nates in a cylindrical neck, 2, and a spherical head, 3.

On the bottom, B, of the can is a cylindrical block or body, D, having its axis coincident with the axis of the can, and said body 1s secured to the bottom of the can by means of rivets, 4. Said body, D, is recessed to re- -ceive` the head, 3, and the neck, 2. `At one side of the axial lineot said body there is a port, 5, extending upwardthrough the-lower face of said body and of proper size to permit `said body andthe can to move down- 'ward` said port receiving the spherical'.

head, 5. From said port there is a passage, 6. extending to and around said aXial line. From said port to and around said'axial line, the bottom of' the body, D, is cut away to a. width a little more than equaling the thickness ot the neck, Q', thus leaving two' lips, 7, .below the passage, (i, between which the necln/Qyinay move horizontally. 0n

said axial line, a recess, 8,- is 'formed tov eX- head rests in said socket, a l allancl-socket joint is formed which will permit the rotation of the canfon sa-idaxial line and will also permit .some` leaning of the can from the vertical. l

The operation is as follows: `When the can is to be placed into the tub, it is moved downward with its axial line at one side of the head, '3, and the neck, '2, the port, 5, being placedv above said head. rihen the canv is moved vdownward until the headis entirely within the port, 5. Then the can is movedto bring its axial line to coincide with the axial line of said head and neck, said hea-d moving through the passage, 6, and said neck moving between the lips, 7, 7.' Such movement is arrested when the head, 3, bears against the wall of the passage, 6, toward whieh'the head has beer, relatively moving. Then the recess or socket, 8, is above the head, and the can may move downward until the upper half of the head rests in said socket.. lee is then packed into the space between the tub vand the can in the usual manner. l'When the can is rotated for freezing, the he'ad, ,3, and thesocket, 8, form' ajournal andbearing" for the' lower end of the can'.

IVhen there is tendency to float, the can can not move upward farther than is permitted by the lips, 7. Said lips bear against the lower portion of the head. At such time lateral movement of the can is prevented by the ice which suirounds the can. That is the case, even when a large portion of the ice has melted. Furthermore, the lips, 7, are concaved around the axial line, such concave portion and the lower portion of the ball making a ball-and-socket joint, so that when the can pulls upward, the lower portion of the head will rest in said concave portion and form an engagement therein which will prevent sidewise movement of the can'. Thus vthere is a balland-socket joint when the can is pressed down by excessive Weight and also when buoyancy lifts the can.

When it is desired to remove the can from the tub, the can is lnoved upward or downward and then sidewise as may be necessary to relatively move the head outward from the axial line of the can through the passage, 6, and then downward through the port, 5.

The base or pedestal, C, may bevaried in height to produce the desired space between the bottom of the tub and the bottom of the can. The length of the neck, 2,-must be sufficient to allow the head, 3, to enter the socket, 8, and to permit the head to move downward and then laterally outward through the passage, 6. That calls for making said neck longer than the height ot' the lips, 7, 7.

The head, 3, andthe body, D, may be said to form a ball-and-socket joint in which the socket is divided into two parts separated from each other, one being the upper part, 8, and the other being the lower part, 9, (the concaved portion vof the lips around the axial line), the passage, 6, leading from between said socket portions, 8, and 9, laterally and opening through one of the faces of said body.
